The Laguna Copperplate Inscription (
Filipino: Inskripsyon sa Binatbat na Tanso ng Laguna,
Malay: Prasasti keping tembaga Laguna) is a legal document
inscribed on a copper plate in 900 AD in
Laguna in the
Philippines. Written in a variety of the
Old Malay language using the
Old Kawi script, it is the earliest known written document found in the Philippines.
The plate was found in 1989 by a laborer near the mouth of the Lumbang River in Wawa
Lumban municipality, Laguna province. The inscription was first deciphered by Dutch anthropologist and
Hanunó'o script expert
Antoon Postma in 1992.
The discovery of the plate is cited as evidence of cultural links between the
Kingdom of Tondo and the various contemporary Asian civilizations, most notably the
Medang Kingdom, the
Srivijaya Empire, and the
Middle kingdoms of India.
